How can I change array key value with php?

Question

For example;

$array[16] = 20;
$array[18] = 8;
$array[27] = 95;

How can I change array[] key value start 0 like this;

$array[0] = 20;
$array[1] = 8;
$array[2] = 95;

I don't know key value. They can be change. $array[16] can be $array[21]

You're not trying to change the order of the array, right? Just reset the first key to zero and increment from there? — Charles

Looping over them will do the trick. But what is the need for resetting the keys — Digitalis

Just assign the values to a new array with the same name:

$array = array_values($array);

You can just use array_values

$array = array_values($array);

I agree, this is the most efficient for PHP imho.

just use array_values like this array_values($your_array) and you will have an array starting from index zero.
